Governing the empire: yam, taxes and Pax Mongolica

Detail

The yam — the courier system

• Genghis Khan built a rapid courier system called the yam. It was a chain of outposts placed at regular distances along the roads.
• At each outpost sat fresh horses and despatch riders. A tired rider handed the message to a fresh one and rode on. So the message never stopped even when the horse did.
• The system was refined after Genghis's death. Its speed shocked travellers who saw it.
• It gave the Great Khans one big power: they could watch and control the farthest corners of a continent-sized empire from the centre.
• Marco Polo recorded that relay stations stood about 25 miles (40 km) apart, and one rider could carry messages up to 300 miles (480 km) in a single day [2].
• A letter from the emperor in Beijing, carried by an envoy holding an imperial pass, could reach the Ilkhanid capital Tabriz — about 5,000 miles away — in roughly one month [2].

Who paid for the yam — the qubcur tax

• The yam was not free. It was paid for by the qubcur tax.
• Qubcur = one-tenth of the nomads' herd (animals or animal produce).
• NCERT's point is key: it was "a levy that the nomads paid willingly for the multiple benefits that it brought". The nomads got fast news, safe roads and a working state in return. So it was not felt as robbery.

Passes and trade taxes

• Travellers on Mongol roads carried a safe-conduct pass:
• paiza in Persian

• gerege in Mongolian

• The pass was a metal tablet. It told every Mongol officer on the road: let this person pass, give them horses and food.

• The Metropolitan Museum of Art (New York) holds a Yuan dynasty (1271–1368) paiza inscribed in the Phakpa script, the script Qubilai Khan had made for his empire [3].
• Traders paid a separate tax called the baj.
• Both the paiza and the baj did the same political work: everyone who used the roads had to accept Mongol authority first.

The cost of conquest

• The other side of this order was terrible destruction.
• Cities destroyed.
• Farmland laid waste.
• Trade and crafts broken up.

• Tens of thousands killed, and even more enslaved. Exact numbers are lost — the surviving reports exaggerate wildly.

• Iran suffered a lasting ecological wound. The underground water channels called qanats (long tunnels that carry water from hills to fields) needed constant repair. With the people gone, nobody maintained them.

• The channels choked.
• The desert crept in.
• Parts of Khurasan never recovered. This damage outlived the war itself.

Pax Mongolica — the Mongol peace

• Once the fighting settled, one single political authority stretched across Asia. Historians call this the Pax Mongolica — the Mongol peace.
• Its first result: Europe and China were territorially linked for the first time under one power.
• Commerce and travel on the Silk Route reached its peak under the Mongols. The Mongols protected caravans and made taxes and tolls uniform across many regions, which is why trade grew [2].
• Classic map-trap for Prelims: the routes no longer stopped in China. They ran north to Karakorum, the heart of the empire. Karakorum, not a Chinese city, was the terminal point.
• Karakorum sits in the Orkhon Valley in Mongolia. Genghis Khan set up his headquarters there in 1220 and used it as the base for invading China [4].
• The Orkhon Valley Cultural Landscape (121,967 hectares) is a UNESCO World Heritage Site, listed for the remains of Kharkhorum, the 13th–14th century Mongol capital, and for showing the link between nomadic herding societies and their administrative and religious centres [5].
• The same valley had earlier been held by the Huns, Turkic peoples, Uighurs and Kidans before the Mongols — nomadic power kept returning to the same grassland [5].

Note: UNESCO and Britannica record that Qubilai Khan moved the capital to Khanbaliq (modern Beijing) in 1267 [4][5]. This does not contradict the NCERT point — Karakorum remained the symbolic heart of the empire and the northern end of the trade routes.

Blunting nomad predation — civil administrators

• A herding army knows how to loot. It does not know how to run cities or collect land tax year after year. The Mongols solved this by hiring experts.
• From Genghis Khan's own reign, civil administrators were recruited from the conquered peoples.
• These officials were then moved around the empire:
• Chinese secretaries served in Iran.

• Persians served in China.

• This shuffling did two things: it gave the Khan trained staff, and it stitched the far-apart dominions into one working system.

• Named examples to remember:
• Yeh-lu Ch'u-ts'ai — he muted Ogodei's rapacity in the 1230s, that is, he cooled down Ogodei Khan's greed for plunder.
• The Juwaini family — played the same restraining role in Iran.
• The wazir (chief minister) Rashiduddin — he drafted Ghazan Khan's speech.

From massacre proposals to peasant protection

• The shift in Mongol thinking over about sixty years is one of the best-marked changes in this chapter.
• 1230s — a Mongol pressure group pushed a plan: massacre the north Chinese peasantry and turn their fields into pasture for the herds. Pure nomad logic — grass matters, farmers do not.
• 1270s — Qubilai Khan appeared as the protector of the peasants and the cities. The same state now defended the farmer it once wanted to remove.

• 1290s — Ghazan Khan in Iran told his Mongol-Turkish commanders not to plunder the peasantry. His argument was practical, not moral:

  "If you insult the peasantry, take their oxen and seed and trample their crops into the ground, what will you do in the future?"

• NCERT's judgement on this speech: it carried such strong sedentary (settled, farming-society) overtones that it "would have made Genghis Khan shudder".

• The reason behind the change is simple: plunder is a one-time income; taxing a living peasant is income every year. Once the Mongols wanted to rule rather than raid, protecting the farmer became self-interest.

Prelims Hooks

• Yam = the Mongol courier/postal relay system, founded by Genghis Khan, with fresh mounts and despatch riders at spaced outposts.
• Qubcur tax = one-tenth of the nomads' herd; it funded the yam.
• Paiza (Persian) = gerege (Mongolian) = the safe-conduct pass carried by travellers.
• Baj = the tax paid by traders.
• Relay stations stood about 25 miles (40 km) apart; a rider could cover about 300 miles (480 km) a day (Marco Polo) [2].
• The Met Museum holds a Yuan dynasty (1271–1368) paiza inscribed in the Phakpa script [3].
• Qanats = underground canals in Iran; unmaintained after the Mongol conquest, leading to desert spread; parts of Khurasan never recovered.
• Under the Pax Mongolica the Silk Route peaked, but routes ran beyond China, north to Karakorum — the empire's heart.
• Karakorum lies in the Orkhon Valley, Mongolia; Genghis set up headquarters there in 1220; the valley is a UNESCO World Heritage Site (121,967 ha) [4][5].
• Yeh-lu Ch'u-ts'ai restrained Ogodei in the 1230s; the Juwaini family did so in Iran; wazir Rashiduddin wrote Ghazan Khan's speech.
• Sequence to memorise: 1230s massacre proposal → 1270s Qubilai protects peasants → 1290s Ghazan Khan's warning speech.

Mains Points

• Administration, not only cavalry, explains Mongol durability. The yam plus the qubcur tax turned speed into a permanent instrument of state control — information moved faster than rebellion could spread. A nomadic empire without such a communication spine could raid but not rule.
• The Mongol state shifted from a predatory to an extractive logic. The move from the 1230s plan to massacre north Chinese peasants, to Qubilai as protector of peasants and cities in the 1270s, to Ghazan Khan's 1290s speech, shows conquerors learning that sustained taxation beats one-time plunder. Useful for any GS-I question on how conquest states become administrative states.
• Costs and gains must be weighed together. The same empire that destroyed cities and let Iran's qanats collapse — an ecological loss from which parts of Khurasan never recovered — also produced the Pax Mongolica that linked Europe and China and pushed Silk Route trade to its peak. A balanced answer must present both, not one.
• Cultural integration through personnel. Recruiting administrators from conquered peoples and posting them across the empire (Chinese in Iran, Persians in China) was a deliberate integrating device. Compare with Indian parallels — the Delhi Sultanate's use of Persian bureaucratic practice and Mughal recruitment across regions and faiths — for a strong comparative paragraph.
